The present invention relates to an infant or adult diaper. More specifically, the invention relates to an infant or adult diaper (10) having a longitudinal centerline (Y) and a lateral centerline (X) perpendicular to the longitudinal centerline (Y) The diaper (10) comprises a topsheet (22) and a backsheet (24) and an absorbent core (20) positioned therebetween, a first longitudinally extending elastic cuff (30a) and a second longitudinally extending elastic cuff And the first and second elastic cuffs (30a, 30b) are positioned to face each other on both longitudinal sides of the top sheet (22), and the diaper (10) has a crotch region (B) positioned between a front region (A) and a back region (C), and first and second longitudinally extending elastic cuffs (30a, 30b ) Each have a crotch region (B ') positioned between a front region (A') and a rear region (C ') and each of these longitudinally extending elastic cuffs (30a, 30b) The region is positioned in each region of the diaper (10) and the first longitudinally extending resilient cuff (30a) and the second longitudinally extending elastic cuff (30b) each extend in the respective longitudinal direction A first longitudinally extending resilient cuff (30a) and a second longitudinally extending resilient cuff (30a) having proximal edges (32a, 32b) attached to the diaper, (30b) each have a distal edge (34a, 34b) forming at least the free flaps (38a, 38b) without the crotch region (B ') being attached to the diaper (10), and the diaper ) Comprises a cuff connector (70) attached to a first longitudinally extending elastic cuff (30a) and a second longitudinally extending resilient cuff (30b), at least one longitudinally extending Each of the extending elastic cuffs (30a, 30b) has a distance to the longitudinal centerline (Y) at each point of the longitudinal centerline (Y), and has at least a first longitudinally extending elasticity With respect to the cuff (30a), at least one first point where the distal edge (34) of
